附加到 Docker 容器的 vscode - 找不到模塊

Question

我在Docker容器內運行vscode調試器，但它開始顯示錯誤：

這很奇怪，因為當我在同一個 vscode window 中打開vscode shell 並導入相同的模塊時，導入工作正常。 所以我需要找到調試器看不到模塊的原因

完整的錯誤代碼：

我的調試器配置文件launch.json

    {
      "name": "Python: File",
      "type": "python",
      "request": "launch",
      "program": "/opt/HonkioServer/entrypoints/api2/docker_entry",
      "justMyCode": true
    }

Answer 1

最后我找到了這個問題的根源 - 它在直接導入到docker-entry文件的文件中，並且項目目錄中的模塊以一種奇怪的方式導入：

# This line adds to modules imports that added below cd two levels up
sys.path.insert(0, os.path.dirname(__file__) + "/../..")

import honkio

但是，在我在vs code中更改此文件后，格式化程序自動更改了行順序，將該行放在所有其他導入的底部。 因此文件導入中斷並顯示module not found error
